The Melancholic Lacuna
There have been countless great tragedies that have befallen the universe. None were quite as impactful as the Lacuna. It was an entire age defined by reclusion and seperation.
We can't know how many died as a result of that singular event, the day that all of our wayhalls shut with nothing but a blink and a pop.
In the initial outset of violence, multiple Banners defended themselves by forcibly closing their Wayhalls, destroying their Indexes. No one expected the entire Wayhall to close as a result of their actions, and thousands of colonies were severed from the entire universe until The Reclamation began.
While widely accepted, there is still debate on whether destroying the Indices is what actually closed the Wayhalls. Rumors persist that there was some other action one of the Banners took which caused it. Most are content just to blame the Sorrows, as they attempted to start a war that forced others to destroy their indexes.
Universal, all inter-system travel was lost.
250 Edenic Years. Reclaimation of lost worlds is still ongoing.
While all Banners have debatable accountability, The House of Sorrows holds blame in most circles.
